Gridded gravity anomaly data for the Former Soviet Union (FSU) and Eastern Europe
has been received by the National Geophysical Data Center(NGDC). The data file contains
1 x 1 degree grid data constructed from several one(1) degree latitude band files.
The observed gravity values are believed to be referenced to the International Gravity
Standardization Net 1971(IGSN71) and the gravity anomaly is believed to have been
computed using the Geodetic Reference System 1967(GRS67) theoretical gravity formula.
